🤓 Based on our data, we think this question is relevant for Professor Tomasik's class at CMU.

Solution: The following reaction is first order, C2H6 → 2 CH3. If the rate constant is equal to 5.5 x 10–4 s–1 at 1000 K, how long will it take for 0.35 mol C 2H6 in a 1.00 L conainer to decrease to 0.20 mol in the same container? A) 65 min B) 17 min C) 53 min D) 4.5 min
